Statement on the Use of American Welding Society Standards

All standards (codes, specifications, recommended practices, methods, classifications, and guides) of the American Welding Society (AWS) are voluntary consensus standards that have been developed in accordance with the mIes of the American National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, Of made part of, documents that are included in federal or state laws and regulations, or the regulations of other governmental bodies, theil' provisions cal'ry the fun legal authority of the statute. In such cases, any changes in those AWS standards must be approved by the governmental body having statutory jurisdiction before they can become apart of those hiws and regulations. In an cases, these standards carry the fulllegal authority of the contract or other document that invokes the A WS standards. Where tlIis contractual relationship exists, changes in or deviations from requirements of an AWS standard must be by agreement between the contracting parties.

AWS American National Standards are developed through a consensus standards development process that brings together volunteers representing varied viewpoints and interests to achieve consensus. While the AWS administers the process and establishes mIes to promote fairness in the development of consensus, it does not independently test, evaluate, or verify the accuracy of any information 01' the soundness of any judgments contained in its standards. AWS disclaims liability for any injury to persons 01' to property, or other damages of any nature whatsoever, whether special, indirect, consequential, Of compensatory, directly or indirectly resulting from the pllblication, use of, or reliance on this standard.

Foreword

This foreword is not part of AWS A5.IIlA5.1IM:201O, SpeeijieationJor Nickel and Nickei-Alloy Weiding Eiectrodes Jor Shielded Metal Are Welding, but i8 included for informational purposes only.

This document is the third revision 10 A5.l1 specificalions which makes use ofbolh U.S. Customary Units and the International System of Units (SI). The measurements are not exaet equivalents; therefore each system must be used independenlly ofthe other, without combining values in any way. In selecting rational metrie units, ANSIIAWS AU, Metric Praetice Guide Jor the Welding lndustry, and International Standard ISO 544, Welding consumables - Technical delivery conditionsJor weldingfi,ller materials ~ Type oJproduct, dimensions. tolerances and markings, are used where suitable. Tables and figures m~ke use of both U.S. Cllstomary and SI units, which with the applic~tion of the specified tolerances provides for interchangeability of products in both the lJ.S. Cuslomary and SI units. This document also relates its classifications to ISO 14172, Weiding consumabies Covered electrodesJor manual metal arc welding oJ nickel and nickel allo)'s - Classijication. The first specification for nickel and nickel-alloy covered electrodes was issued in 1954 by a joint committee of the American Society for Testing and Materials and the American Welding Society. The first revision in 1964 was also the result of the cooperative effort. This revision i8 the seventh prepared entirely by the AWS A5 Committee on Filler Metals and AlIied Materials. This revision contains new dassiJications ENiCrFe-13 and ENiCrMo-22. The Rmmding-Ojf Proeedure has been revised. Based on new Rmmding-Ojf Procedure, tensile strength oJ ENiCrMo-ll in Table 4 has been rounded up Jrom 585 MPa to 590 MPa, because new rounding ojfproeedure requires rounding to the nearest 10 MPa Substantive changes are shown in the !talie Jont.

7. Summary of Tests The tests required for classifieation are speeified in Table 2. The purpose of these tests is to detennine the chemieal eomposition, the meehanieal properties and soundness of the weid metal, and the lIsability of the eleetrode. The base metal for the weId test assemblies, the welding and testing proeedures to be employed, and the results required are given in Clause 9, WeId Test Assemblies, throllgh Clause 13, Bend Test.

8. Retest 8.1 If the results of any test fail to meet the reqllirement, that test shaU be repeated twiee. The results of both retests shall meet the requirement. Specimens for retest may be taken from the original test assembly, or from one or two new test assemblies. For chemical analysis, retest neeel be only for those specifie elements that failed to meel the test requirement.

8.2 If the results of one or bOlh retests fail to meet the requirement, the material under test shall be considered as not meeting the requirements of this speeifieation for that classifieation. ( 8.3 In the event that, during preparation or after eompletion of any test, it is clearly determined that preseribed or proper proeedures were not followed in preparing the weId test assembly or test speeimen(s) or in eondueting the test, the test shall be eonsidered invalid, without regard to whether the test was aetually eompleted, or whether test results met, or failed to mee!, the requirement. That test sha1l be repeated, following proper prescribed procedures. In this ease, the reqllirement for doubling of the number of test specimens does not apply.

9. WeId Test Assemblies 9.1 To perform all required tests as speeified in Table 2, a minimum of one weId test assembly is required. Two, or even three, may be neeessary (aeeording to the classifieation, size, and manner in which the testing is eondueted, i.e., with respeet to alternative options). The weId test assemblies are identified as follows:

(1) The weid pad in Figure 1 for ehemical analysis of the undillited weid metal

(2) The groove weId in Figure 2 for meehanical properties and sOllndness (3) The groove weid in Figure 3 for radiographie soundness (

The sampIe for ehemieal analysis may be taken [rom a low dilution area in the groove weId in Figure 2, Of from the redlleed seetlon of the fraetured tension test specimen, thereby avoiding the need to make the weid pad. In ease of dispute, the weid pad shall be the referee method.

9.2 Preparalion of eaeh weId test assembly shall be as preseribed in 9.3, 9.4.1, and 9.4.2. The base meta1 for eaeh assembly shall meet the requirements of the appropriate ASTM specifieation shown in Table 3 or an equivalent specification. Testing of assemblies shall be as prescribed in Clauses 10 through 13.

9.3 Weid Pad. A weId pad shall be prepared as specified in Table 2 and shown in Figure 1, exeept when one of the alternatives in 9.1 (taking the sampIe from the weId metal in the groove or from the tension test specimen) is seleeted. Base metal of any convenient size, of the type specified in Table 3, shall be used as the base for the weid pad. The surfaee of thc base metaion wh ich the filler metal is deposited shal] be clean. The pad shall be welded in the flat position wirh multiple beaels and layers to oblain undiluted weid meta!. The type of currenl and range of amperage used for welding shall be as recommended by the manufacturer. The preheat temperature shall be not less than 60F [16C] and the interpass temperature shall not exceed 300F [150C]. The slag 8hall be removed after euch pass. The pad may be quenehed in wate!' (temperature above 60F [16C]) between passes. The dimensions of the eompleted pad shall be as shown in Figure I for eaeh size of eleetrode. Testing of this assembly 8hall be as specified in Clause 10, Chemieal Analysis.

10. Chemieal Analysis 10.1 The sampie for analysis shall be taken from weld metal obtained from the weId pad, the reduced section of the fraetured tension test specimen, 01' a low-dilution area of the groove weid in Figure 2. The top surface of the pad described in 9.3 and shown in Figure I (when the pad is used), shall be removed and discarded. A sampie for analysis shall be obtained from the underlying metal by any appropriate mechaniealmeans. The sampie shall be free of slag.

For electrodes smaller than 5/32 in [4.0 mm], the sampIe shall be taken at least 3/8 in [9.5 mm] [rom the nearest surface of the base meta!. For electrodes 5/32 in [4.0 mm] and larger, the sampIe shall be taken at least 3/4 in [19 mm] from that surface. If carbon-steel base metal is used in the chemical analysis test pad, see Note "a" in Table 3. The sampie from the reduced section of the fractured tension test specimen and the sampie from a low-dilution area of the groove weid shall be prepared for analysis by any suitable mechanical means.

10.2 The sampie shall be analyzed by accepted analytical methods. The referee method shall be ASTM E 1473, supplemented by ASTM E 1019 and ASTM E 354 for nickel base alloys, and ASTM E 76 for nickel copper alloys, as appropriate.

10.3 The results of the analysis shall meet the requirements of Table 1 for the classification of electrode under test.

11. Radiographie Test 11.1 The radiographie soundness test weid described in 9.4.2 and shown in 3 (01' the groove weId described in 9.4.1 and shown in Figure 2, when that is desired and is permitted by note c ofTable 2), shall be radiographed to evaluate the usability of the electrode. In preparation for radiography, the backing shall be removed and both surfaces of the weid shall be machined 01' ground smooth and flush with the original surfaces (except as noted) 01' the base metal Of with a uniform reinforcement not exceeding 3/32 in [2.5 mm]. It is permitted on bolh sides of the test assembly to remove base metal to a depth of 1/1 in [1.5 mm] nominal below the original base metal surface in order to facilitate backing and/or bllildup removal. Thickness of the weid metal shall not be reduced by more than 1116 in [1.5 mm] less than the nominal base metal thiekness. Both surfaces of the test assembly, in the area of the weId, shall be smooth enough to avoid difficully in interpreting the radiograph.

11.2 The weid shall be radiographed in accordance with ASTM E 1032. The quality level of inspection shall be 2-2T.

11.3 The electrode meets the requirements of lhis specification if the radiograph shows tbc following:

(1) No cracks, no incomplete fusion, and no incomplete penetration

(2) No slag inc1usions in excess of those permitted by Note 4 to the radiographie standards in Figures 4 through 8, according to the size of the electrode

(3) No rounded indications in excess of those permitted by the radiographie standards in Figures 4 through 8, according to the thiekness of the test assembly, or the alternative method of evaluation in 11.3.1

In evaluating the radiograph, 1 in [25 mm] of the weId on each end of the test assembly shall be disregarded.

11.3.1 The alternative method of evaluation involves calculation of the tOlal area of the rounded indications as tbey appear on the radiograph. Tbis total area shall not exceed 1 percent of the thickness of the test assembly multipliecl by the length of the weId used in the evaluation (length of the weId in the test assembly minus 1 in [25 mm] on each end). Tbe value given in Note 3 to each of the Figures (4 throllgh 8) has been calculated for 6 in [150 mm] of weId (an 8 in [200 mm] long test assembly). The value for weid lengths other than this will differ on a linearly proportional basis.

11.3.2 A rounded indication is an indication (on the radiograph) whose length is no more than three limes its width. Rounded indications may be circular, elIiptical, conical, or irregular in shape, and they may have tails. The size of a rounded indication is the largest dimension of the indication including any tail that may be present. The indications may be of porosity 01' slag. The total area of the rounded indications for the alternative method shan not exceed the values given in Note 3 to the radiographie standards (Figures 4 through 8). Indications whose largest dimension does not exceed 1/64 in [0.4 mm] shall be disregarded. Test assemblies with rounded indications larger than the largest indications permiued in the radiographie standards do not mect the requirements of this specification.

Annex A (Informative) Guide to AWS Specification for Nickel and Nickel-Alloy Welding Electrodesfor Shielded Metal Arc Welding

This annex is not part of AWS A5.1l/A5.11M:2010, Specificationfor Nickel and Nickel-Alloy

Welding Electrodes for Shielded Metal Are Welding, but is included for informational purposes only.)

Al. Introduction The purpose of (his guide is to correlate the electrode c1assifications with their intended applications so the specification can be used effectively. Reference to appropriate base metal specifications is made whenever that ean be done and when it would be helpfuL Such references are intended only as examplcs rather than complete listings of the base metals for which each filler meta) is suitable.

A2. Classification System A2.1 The system for identifying the electrode classifieations in this specification follows the standard pattern used in other A WS filler metal specifications. The letter HE," at the beginning of each classification designation stands for eleetrode.

A2.2 Since the electrodes are c1assified aeeording to the ehemical composition of the weid meta! they deposit, the ehemical symbol "Ni" appears right after the " as a means of identifying the electrodes as nickel-base a1\oys. The other symbols (Cr, Cu, Fe, Mo, Si, W, and Co) in the designations are intended to group the electrodes aeeording to their principal a1\oying elements. The individual designations are made up of these symbols and a nllmber at the end of the designation (ENiMo-1 and ENiMo-3, for example). These nllmbers separate one eomposition from another, wilhin a group, and are not repeated within that group.

A2.3 From an application point of view, the eleetrode classifications in this specification have eorresponding classifications in AWS A5.14/A5.l4M, Specificationfor Bare Nickel and Nickel-Alloy Welding Electrodes and Rods, for those eases in which there is a eorresponding applieation for a bare electrode or rod (ER). Table A.l eorrelates the eovered electrode c1assifications in this edition with the cOl'responding ER classification in AWS A5.14/A5.l4M.lt also lists the ellrrent designation for each classification as it is given in a prominent and pertinent military speeitication, when such a designation exists.

A2.4 An international system for designating welding filler metals developed by the International Institute of Welding (nW) is being adopted in many ISO specitications. Table Al shows those used in ISO 14172 specifieation fol' comparison with comparable classifications in this specitication. To understand the pl'oposed international designation system, one is referred to Table IOA of the annex of the A WS doeument IFS :2002, International Index ofWelding Filler Metal Classijications.

A3. Acceptance Aceeptanee of a11 welding materials elassified under this speeification is in accordance with AWS A5.01M/A5.01 (ISO 14344). as the specifieation states. Any testing a purchaser requires of the supplier, for material shipped in accordanee with this specification, needs to be clearly stated in the purehase order, aeeording to the provisions of AWS A5.01MI

the requirements of the specification. The only testing reqllirement implicit in this certification is that the manllfaeturer has aetually condllcted the tests required by the specification on material that is representative of that being shipped and that the material met the requirements of the speeification. Representative material, in this ease, is any produetion run of that classification using the same formulation. Certification is not to be construed to mean that tests of any kind were neeessarily conducted on sampies of the specifie material shipped. Tests on such material may or may not have been conducted. The basis for the certification required by the specification is the c1assification test of "representative material" cited above, and the "Manufacturer's Quality Assurance System" in AWS A5.0IM/A5.0l (ISO 14344).

AS. Ventilation During Welding AS.l Five major factors govern the quantity of fumes in the atmosphere to which welders and welding operators are exposed during welding:

(1) Dimensions of the space in which welding is done (with special regard to the height of the ceiling);

(2) Number of welders and welding operators working in that space;

(3) Rate of evolution of fumes, gases, or dust, aceording to the materials and processes involved;

(4) The proximity of the welders or welding operators to the fumes as they issue from the welding zone, and to the gases and dust in the space in which they are working; and

(5) The ventilation provided to the space in which the welding is done.

A5.2 Amedcan National Standard ANS I Z49.1 (published by the American Welding Soeiety), discusses the ventilation that is required cluring welding and should be referred to for details. Attention i8 clrawn particularly to the section of that doeument dealing with ventilation.

A6. Welding Considerations A6.1 Before welding or heating any nickel-base alloy, the material must be clean. Oil, grease, paint, lubricants, marking pencils, temperature-indicating materials, threading compounds, and other such materials frequently contain sulfur, lead, or silver, which may caUBe eracking (embrittlement) of the base metal or [he weId metal if present during welding or heating.

A6.2 Electrodes of some of the classifications are used for dissimilar metal welds. When making such welds, it is important to obtain as little dilution as possible from the dissimilar metal member (steel, for example). This can be done by traveling slowly to deposit a thicker bead and to dissipate the energy 01' the arc against the molten weId metal or the nickel base metal, rather than the dissimilar metal member.

A6.3 Most of the electrodes in this specification are intended to be used with DCEP (Direet Current, Eleetrode Positive) polarity. Some electrodes may be designed to also operate on alternating current whieh makes them desirable for minimizing are blow. The electrode manufacturer should be eonsulted to determine if a parlicular product is designed to be used with alternating current.
